Upload raw footage or paste a script, then tell the AI video editor what you want changed in plain text. It cuts, captions, and polishes your video into publish-ready content—no video editing experience or complex editing software needed.
Key featuresFeatures of the AI video editor
Text-based AI video editing commands
Type a prompt describing the change you want, like removing a section, tightening pacing, or rearranging scenes, and the editor applies it as a precise cut. Deleting words in the transcript trims the matching footage, so you make edits the way you edit a document.
Automatic captions and subtitles
Generate accurate captions for any clip in seconds, then adjust wording, timing, and customizable caption styles with text animation before export. Because captions come from the built-in subtitle generator, spoken audio becomes clean on-screen text that keeps videos watchable with the sound off on social feeds.
AI audio cleanup and natural voiceovers
Clean up background noise, balance levels, and apply studio-grade audio enhancement without an engineer. Need a new voiceover? Swap or re-record lines using AI voice Cloning for natural-sounding narration that matches the original speaker across every revision.
One-click resizing for every platform
Reformat one edit into vertical, square, and widescreen versions in a single pass, or drag and drop elements to fine-tune each layout. The editor reframes subjects and repositions captions effortlessly for TikTok, YouTube, LinkedIn, and email, so one source video covers every channel.
AI B-roll and cinematic scene fills
Fill gaps in your footage with AI-generated scenes instead of stock video clips. Type a text prompt and Seedance 2.0 produces cinematic video with accurate motion and lighting that matches your cut, so transitions, intros, and cutaways no longer require a second shoot.
Use cases
Cutting a webinar into shorts once took a full day of scrubbing timelines. The clip generator finds the strongest moments for you, producing captioned, reframed video clips ready for Reels, Shorts, and TikTok, so one recording becomes a week of engaging content.
Offers change faster than agencies can re-edit. Swap scenes, update text, apply video effects, and test new hooks on a promo video in minutes, so campaigns stay current without new production budgets or reshoots.
Screen recordings full of pauses and filler make weak training. Tighten each step, narrate with a cloned voice, and standardize style across modules so teams get clear how-to and explainer videos that reduce repeat support questions.
Editing an hour-long episode manually takes up a full workday. AI removes silences and filler words, cleans audio, and captions the result, so creators can publish more podcasts and YouTube episodes without hiring an editor.
Reshooting content for each market is unaffordable for most teams. Run any finished edit through the AI video translator and publish the same video in over 175 languages with matched lip movement.
Product videos need constant updates as listings, prices, and features change. Replace scenes, swap video backgrounds, add text overlays, animate stills with image-to-video, and resize for marketplaces and social ads in one workspace instead of rebuilding each variant.
How it worksHow AI video editor works
Go from raw footage to a polished, ready-to-publish video in four steps, with AI-powered tools in a single workflow handling the cuts, captions, and formatting.
Upload a recording or screen capture. The editor creates a transcript and scene overview.
See your video as text and scenes. Apply a brand template, then mark the sections you want to change.
Type prompts to cut, caption, clean audio, add effects, and resize. Each command becomes an edit.
Finalize the cut, then export in HD or 4K as MP4, plus sized versions for each channel.
An AI video editor is a tool that cuts, captions, and enhances videos from a plain language prompt instead of manual timeline work. The AI video editor makes studio-quality results possible in minutes by automating complex tasks like trimming, syncing, and captioning, so you edit videos with AI instead of scrubbing a timeline.
Yes. Every AI edit stays fully adjustable, so you keep creative flexibility over the result. Fine-tune individual cuts, captions, scene order, and audio after each command; AI handles the repetitive editing tasks while you keep frame-level control.
Open the transcript and AI automatically flags filler words, pauses, and silences. Delete them as text and the matching footage is trimmed, turning hours of manual scrubbing into a few minutes of review.
